Set Up the /etc/system File

HDLM uses a maximum of 8 KB of the stack for the kernel thread. Add the
usage of HDLM to this maximum value, specify that total value as the stack
size for the kernel thread, and then install HDLM. In Solaris 10,
default_stksize has priority over lwp_default_stksize. Therefore, if
default_stksize is specified in /etc/system, add 8 KB to the value
specified in default_stksize. If the documentation for the volume manager
or file systems that use HDLM devices specify that the stack size for the
kernel thread is to be expanded, the value mentioned in the documentation
must be also added to the stack size.
The procedure for increasing the stack size of the kernel thread from the
default size in a system with a 64-bit kernel is as follows:
In Solaris 8 or Solaris 9
Add set lwp_default_stksize=0x6000 to /etc/system, and then restart
the host.
In Solaris 10
Add one of the following parameters to /etc/system, and then restart the
host:

The default_stksize parameter takes precedence when both
parameters are specified.

Set Up the /etc/syslog.conf File

The dlmsetconf utility and the DLMgetras utility for collecting HDLM error
information output messages to syslog. See the /etc/syslog.conf file
(system log configuration definition file), and then check if it is set so that
messages with a level of "Error" or higher are to be output.
Make sure that the /etc/syslog.conf file contains the following
configuration entry. We recommend setting the output destination for *.err
in the /etc/syslog.conf file to the default /var/adm/messages directory.
*.err;kern.debug;daemon.notice;mail.crit;
When you collect audit log data, we recommend that you use any of the
extended facilities (local0 to local7) as the exclusive output destination for
the data. We also recommend that you specify info as the severity level for
To switch to the 64-bit kernel mode:
If Solaris is running, execute the following command:
# reboot -- "boot-device kernel/sparcv9/unix other-boot-
options"
To boot at the ok prompt, execute the following command:
boot boot-device kernel/sparcv9/unix other-boot-options
set lwp_default_stksize=0x8000
set default_stksize=0x8000
